For downward compatibility, the wires are all large-diameter wires before being stretched, the wires need to be stretched into thin wires with different diameters according to the requirement on the flexibility of the wires, and the higher the flexibility requirement is, the thinner the wires need to be stretched. Since the toughness of the wire is limited and the wire is easily broken when the diameter is too much shrunk at one time, when a thick wire is stretched into a thin wire, it is generally necessary to stretch the wire many times, and the number of times of stretching increases as the wire stretching diameter decreases.
